In present day constructions concrete is chosen as one of the best choices by civil engineers in construction materials. The concept of sustainability is touching new heights and many green building materials are tried and tested as partial replacement for the cement. One of the bye-products is Condensed Silica Fume (CSF) which enhances the durability and strength of the concrete. In the present investigation the strength of M60 and M70 concretes with the use of micro silica and in combination with colloidal nano-silica was used to study the mechanical properties. It is found from the experimental investigation that concrete composites with superior properties can be produced with the combination of micro-silica and nano-silica.
